1. Mineral water production line cleaning

1. Open the control panel of the pure water equipment and turn on the air switch to turn on the power.

2, rolling manganese sand filter multi-way valve head to point the pointer to "backwash (BACK WASH)", open the pure water equipment booster pump switch for manganese sand filter backwashing process, the time is 5 minutes.

3. Closed pure water production equipment booster pump switch ends the backwashing procedure of the manganese sand filter.

4, rolling manganese sand filter multi-way valve head to point the pointer to "FAST RINSE", open the booster pump switch for manganese filter washing process, the time is 5 minutes.

5. Close the booster pump switch to end the normal washing process of the manganese sand filter, then roll the multi-way valve head of the manganese sand filter to point the pointer to "FILTER", and the manganese sand filter cleaning is finished.

6. Rolling quartz sand filter multi-way valve head points the pointer to “BACK WASH”, and turns on the booster pump switch to perform the quartz sand filter backwashing process for 5 minutes.

7. Closed pure water production equipment booster pump switch ends the backwashing procedure of quartz sand filter.

8. Rolling quartz sand filter multi-way valve head points the pointer to “FAST RINSE”, and turns on the booster pump switch to perform the quartz sand filter washing process for 5 minutes.

9. Closed pure water equipment booster pump switch ends the quartz sand filter's washing process, then rolls the quartz sand filter's multi-way valve head to point the pointer to "FILTER", and the quartz sand filter cleaning ends.


Second mineral water production line disinfection

1. Disinfection of production water In the international arena, the commonly used method in the disinfection of drinking water is disinfection of chlorine dioxide disinfectant. Because the chlorine dioxide disinfectant is safe, efficient, broad-spectrum and fast in action, it will not cause tri-materials (teratogenic, carcinogenic, sudden changes) and no impact on the human body at the time, but is listed by the World Health Organization. It is a Class A1 safe and effective disinfectant, and can remove the odor and colored iron and manganese ions in the water to improve the water quality. It can directly participate in water sterilization with 0.5-1.0mg/L chlorine dioxide.

2. The handling of microbial contamination of filling equipment, pipeline system, water treatment system equipment, disinfection and filling equipment, pipeline system and water treatment system equipment is mainly practical chemical disinfectant, reservoir, stainless steel pipeline, water treatment equipment (including ultrafiltration system), batching tank, pipeline disinfection concentration of 50mg / L, can be wiped, sprayed, soaked circulation and other methods for sterilization, after five minutes with pure water or sterile water wash clean. Disinfect once a week. In order to reduce the oxidation of the membrane system, care should be taken to avoid equipment containing membrane systems. 3. The barrels and caps of the PE buckets and barrel lids are cleaned and the sanitary conditions are poor. Whether the cleaning and disinfection of the empty barrels is complete is directly related to the quality of the products. It is the main point of quality control of drinking water production products.

(1), the dynamic cycle disinfection of the recovered PE barrels with alkaline washing water and then use 50-80mg / L chlorine dioxide disinfectant through the active bottle washer high-pressure spray disinfection, disinfection time is 10 - 15 seconds. After disinfection, it can be washed without pure water, and can be filled after slightly controlling the disinfectant in the dry bucket. A very small amount of chlorine dioxide in the water can be used as a preservative to extend the shelf life of pure water. The disinfectant can be recycled, and every 20 hours, the demand increases the amount of the original disinfectant by 20% - 30% as a consumption supplement to increase the concentration of the disinfectant into 2000 mg / L. The disinfectant is manufactured daily. The more polluted barrels and bottles need to be soaked in 50mg/L chlorine dioxide disinfectant for 5-10 minutes, and then dynamically disinfected by the above method.

Note: In order to reduce the chlorine dioxide overflow during the washing process, the washing machine should be enclosed in a small room, and the small exhaust fan on the top of the small room should be exhausted. (2) Static immersion disinfection If there is no dynamic disinfection equipment. After washing the barrel, it can be soaked in 50~60mg/L chlorine dioxide disinfectant for 5~10 minutes, and the disinfectant in the dry barrel can be filled.

Disinfection of the lid and cap: soak for 5 to 10 minutes with 50-80mg/L chlorine dioxide disinfectant. 4, the production environment disinfection production environment disinfection mainly includes the production of air disinfection, wall, floor and equipment surface disinfection. There is mold in the air in the filling workshop, which is the primary way to contaminate pure water mold. The workshop uses two methods for disinfection. One is to spray chlorine dioxide into 100 mg/L disinfectant solution, and continue to adhere to the disinfection time of 10-20 minutes after spraying; secondly, the chlorine dioxide is formulated into 3000 mg/L disinfectant for fumigation (200g). Applicable to 4000 m3 space), pay attention to closing doors and windows, air supply equipment and UV lamps during fumigation. If fumigation can enhance indoor air circulation, the effect is better. Disinfect each time before the sunrise. 5. Disinfection of the hands and costumes of the operators during the production process

The operator's clothing has the presence of mold and should be treated with disinfection. Wash your hands carefully with hand sanitizer twice, then wash your hands in 80-100mg/L chlorine dioxide disinfectant for 1 minute. After washing, it will be naturally dry. After washing the overalls, soak them in 50mg/L chlorine dioxide disinfectant for 5 minutes, dry or dry.
